[1] Prolacerta and Kadimakara were closely related to the Archosauriformes, a successful group which includes archosaurs such as crocodilians, pterosaurs, and dinosaurs.
[1] The Rewan Formation corresponds to the Induan age at the very beginning of the Triassic Period, about 251 million years ago, when life had only begun to recover from the Permian-Triassic extinction.
[2] Like other animals preserved in the Rewan Formation, remains of Kadimakara were encrusted in hematite and had to be carefully prepared with thioglycollic acid.
[1] Kadimakara was roughly half the size of its larger relative Prolacerta, but was otherwise quite similar based on the structure of its preserved skull bones.
In the middle of their suture (line of contact) was a hole known as a pineal foramen, which in some modern reptiles contains a sensory structure colloquially known as a "third eye".
All of these parietal features are also shared by Prolacerta, and their presence (or lack thereof) links Kadimakara with that genus in the family Prolacertidae.
The original describer of Kadimakara, Alan Bartholomai, considered it a postorbital bone which forms the rear edge of an unusually elongated orbit.
This reinterpretation means that the orbit had a rounder and much less unusual shape than that of Bartholomai's original reconstruction, as the actual postorbital bone was positioned further forward on the skull.
The ventral process (lower branch) of the squamosal, which extends onto the cheek region of the skull, contacts a smaller crescent-shaped bone near the jaw joint.
However, a 1975 analysis by Chris Gow provided a more specific explanation, arguing that the teeth of Prolacerta (and Kadimakara, as Bartholomai notes) were particularly similar to those of 'thecodonts', a group of carnivorous reptiles now known as archosauromorphs.
During this transition, Kadimakara and Prolacerta were kept in a group known as Prolacertiformes, which contained other long-necked early archosauromorphs such as Protorosaurus, Macrocnemus, and Tanystropheus.
[3] This changed in 1998, when a study by David Dilkes found that Prolacertiformes was a polyphyletic group, consisting of various reptiles only distantly related to each other.
Most notably, Prolacerta was found to be more closely related to the advanced Archosauriformes rather than Protorosaurus and other long necked basal archosauromorphs (collectively termed "protorosaurs").
[3] As a result, it was unknown whether Kadimakara was legitimately a close relative of Prolacerta or simply an unrelated basal archosauromorph incorrectly allied with it, as is the case with the protorosaurs.
In each of the three analyses, Kadimakara was placed as the sister taxon to Prolacerta, with these two genera forming the family Prolacertidae, positioned near Archosauriformes as Dilkes (1998) and other studies claimed previously.
